[0021] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0022] See also Figure 1-Figure 4 In order to solve the problem that it is difficult to adjust the space inside the existing aircraft external luggage compartment, which may make the luggage unable to be effectively fixed during the flight, causing the luggage to move or shake in the compartment, and even cause danger, the following preferred technical solutions are provided:

[0023] A space adjustment structure for an external luggage compartment of an aircraft comprises a compartment body 1, and a mounting plate 2 arranged at the upper end of the compartment body 1, a compartment door 3 is installed on one side of the compartment body 1, an adjustment mechanism 4 is installed in the cavity of the compartment body 1, the adjustment mechanism 4 comprises a receiving plate 41 installed on the bottom plate of the cavity of the compartment body 1, the inner wall of the receiving plate 41 is rotatably connected to a first screw rod 42, a middle connecting rod 43 is installed at one end of the first screw 42, an end of the middle connecting rod 43 away from the first screw 42 is fixedly connected to a second screw 44, a first slider 45 is threadedly connected to the outer wall of the first screw 42, a second slider 46 is threadedly connected to the outer wall of the second screw 44, and the upper ends of the first slider 45 and the second slider 46 are both fixedly connected to a partition body 47.

[0024] The size of the partition body 47 matches the inner cavity size of the cabin body 1, the first slider 45 and the second slider 46 are both slidably connected to the bottom plate of the inner cavity of the cabin body 1, the first screw 42 and the second screw 44 are symmetrically distributed about the center of the middle connecting rod 43, and the outer wall thread structures of the first screw 42 and the second screw 44 are opposite, and the end of the second screw 44 away from the middle connecting rod 43 is fixedly connected to a servo motor.

[0025] A control block 48 is provided at one end of the first screw rod 42 away from the middle connecting rod 43, and an inner screw rod 49 is fixedly connected to one end of the control block 48. The outer wall of the inner screw rod 49 is threadedly connected to the inner wall of the first screw rod 42. A fixing groove 410 is provided at one end of the middle connecting rod 43 close to the first screw rod 42. The inner screw rod 49 penetrates the inner wall of the first screw rod 42, and the end of the inner screw rod 49 away from the control block 48 is threadedly connected to the fixing groove 410. The first screw 42 is connected to the middle connecting rod 43 through the inner screw 49.

[0026] Specifically, after the luggage is placed in the inner cavity of the cabin body 1, the servo motor can be driven to drive the second screw 44 to rotate. The second screw 44 drives the first screw 42 to rotate at the same time through the middle connecting rod 43. Since the outer wall thread structures of the first screw 42 and the second screw 44 are opposite, the first slider 45 and the second slider 46 drive the partition body 47 at their upper ends to move closer to or away from each other, thereby achieving the purpose of adjusting the space inside the cabin, solving the problem that the existing aircraft external luggage cabin is difficult to adjust the internal space, which may make the luggage unable to be effectively fixed during the flight, causing the luggage to move or shake in the cabin, and even causing danger.

[0027] At the same time, the control block 48 can be rotated to drive the inner screw 49 to rotate and move on the inner wall of the first screw 42, so that the inner screw 49 is separated from the fixing groove 410. At this time, the first screw 42 is separated from the connection with the middle connecting rod 43, so that when the second screw 44 is rotated at this time, the first screw 42 will not rotate therewith, so as to better cooperate with the adjustment space and have a significant effect.

[0028] To sum up: after the luggage is placed in the inner cavity of the cabin body 1, the servo motor can be driven to drive the second screw 44 to rotate, and the second screw 44 drives the first screw 42 to rotate at the same time through the middle connecting rod 43. Since the outer wall thread structures of the first screw 42 and the second screw 44 are opposite, the first slider 45 and the second slider 46 drive the partition body 47 at their upper ends to move closer to or away from each other, thereby achieving the purpose of adjusting the space in the cabin. At the same time, the control block 48 can be rotated to drive the inner screw 49 to rotate and move on the inner wall of the first screw 42, so that the inner screw 49 is disengaged from the fixed groove 410. At this time, the first screw 42 is disengaged from the middle connecting rod 43, so that when the second screw 44 is rotated at this time, the first screw 42 will not rotate with it, so as to better cooperate with the adjustment of the space.
